Enum RelationKind 

pub enum RelationKind {
    Link,
    Inherits,
}

The kind of a relation — link or inheritance.

Display writes "link" / "inherits". Derives Ord + PartialOrd with Link declared before Inherits, so derived Ord puts link relations before inherits relations for the same source under D6’s tuple sort (source, kind, field, target). Copy / Eq cover invariant assertions. No serde derive.

Variants

Link

A link field on the source resource-type points to the target resource-type. The field name labels the relation. Display: "link".

Variant order is load-bearing: Link is declared before Inherits so that derived Ord gives Link < Inherits, making link relations sort before inherits relations for the same source (D6).

Inherits

The source resource-type extends the target as a superclass. Display: "inherits".
